Title: Sharpening device for gramophone needles and the like
IPC: B24B19/16
Filed: 1922-05-15
Abstract: 194,592. Partridge, W. W. May 15, 1922. Needles and the like, pointing.-A device for sharpening gramophone needles &c. comprises an abrading-wheel A journaled in a frame D and adapted to be driven by frictional contact with the rotating table of a gramophone, or other rotating body, or by other means. The needle &c. J to be sharpened is held in a spindle G running in a double bearing F which is pivoted to an arm E. The spindle G carries a wheel H, which is adapted to contact with the abrading- wheel A and to be driven thereby, the wheel H being of such size that, when it and the needle both rest on the same surface of the wheel A, the needle point will be ground at the correct angle. The arm E is pivoted at L on a piece M, which is adjustably secured to the frame by a screwed pin N, and the wheel H and the needle are held down on the abrading-wheel by a spring K. In the abrading-wheel is a central recess, in which is a pin O; by depressing the outer end of the arm E, the wheel H moves into the recess, lifting the needles and engaging the pin O, thereby causing the abrading-wheel to act as a brake to the rotating part which drives the wheel. The frame D is mounted to swivel about a pin R on a base P, which is secured to the base of the gramophone or other surface, whereby the abrading-wheel may be held in, or out of, contact with the rotating driving-member by means of a spring i secured at one end to the base P and at the other end to a pin T. This pin is carried by a lever S, secured to the pin R, and projects through a curved slot in the base P and into contact with the frame D; the frame may be removed from the base by removal of a nut U, and a brake lever Z, Fig. 5, may be substituted therefor to be used with the gramophone.

Filed: 1977-03-31
Abstract: 1531968 Radar RAYTHEON CO 31 March 1977 13695/77 Heading H4D Digital pulse compression radar wherein an uncompressed transmitted chirp pulse and a selected uncompressed received chirp pulse are digitally processed and cross-correlated in the frequency domain comprises means to eliminate Fresnel ripples in the frequency spectrum of the correlated chirp pulse which ripples would tend to distort the waveform of the compressed pulse in the time domain. The transmitted chirp pulse in the form of a discrete series of complex numbers in the time domain generated from ROM 13, is transformed in discrete fourier transform circuit 17 to the frequency domain, is converted, to the complex conjugate form, modified to mirror and thereby to cancel the Fresnel ripples in the received signal spectrum, in multiplier 35, and is stored in memory 30. The received signal is digitized, range gated and fed to D.F.T. 33, the discrete signal spectrum thereof so produced being cross correlated with the stored modified conjugate signal stored in memory 30 to produce a spectrum of theoretical squared off shape. Weighting function (e.g. Hamming) stored in memory 47 is then multiplied with signal at 45, the weighted spectrum is then inversely fourier transformed at 49 and fed as a compressed received pulse to conventional analogue utilization circuits.

Title: Improvements in or relating to production of alcohols and organic acids from oxygenated organic compounds
IPC: C07C51/15
Filed: 1950-06-01
Abstract: The proportion of alcohols or acids in an aqueous mixture containing alcohols, acids, aldehydes, and ketones is increased by treating with CO2 or a mixture containing H2 and CO2 whose H2 content is less than 10 mol. per cent when acids are desired and is at least equal to the CO2 content when alcohols are desired, in the presence of a hydrocarbon synthesis catalyst at about 145-360 DEG  C. and from about 200 p.s.i. upwards.  The initial mixture may be the primary oil obtained by a Fischer-Tropsch synthesis or the aqueous phase thereof together, if desired, with the oxygenated products from the oil phase.  Oxidation products of hydrocarbons or any mixtures of the oxygenated compounds, either aliphatic, cycloaliphatic or aromatic, may be treated.  The acids may be removed prior to the treatment. When alcohols are desired, the feed should generally contain at least 5 per cent of the oxygenated compounds and at least 5 per cent water. For acids, water need not be present. The process is preferably effected in a hydrocarbon synthesis type reactor with a fluidized catalyst, e.g. iron.  To obtain acids, the CO2 : H2 ratio may range from about 2 : 1 at 200 p.s.i. and 150 DEG  C. to about 5 : 1 at 450 p.s.i. and 315 DEG  C. For alcohols, the ratio may be not more than about 1 : 2 at 200 p.s.i. and 150 DEG  C.  Optimum increases in both alcohol and acid concentrations are obtained with CO2, H2 mixtures constituting about 50-67 mol. per cent of the total feed.  Fixed bed and liquid phase operations may be employed.  Other catalysts specified are cobalt, nickel, and ruthenium.  In an example, a primary water phase from a hydrocarbon synthesis effected at 315 DEG C. and 450 p.s.i. is treated with an equimolar amount of CO2, H2 mixture containing equal amounts of CO2 and H2 in the presence of fluidized mill scale, the products being separated and undesired compounds recycled to give an increased yield of ethanol.  A similar example using CO2 only shows an increased yield of acetic acid.

Title: Improvements in or relating to hydrostatic transmissions
IPC: F16H61/46
Filed: 1960-04-21
Abstract: 876,440. Hydraulic transmission of power. INTERNATIONAL HARVESTER CO. April 21, 1960 [April 22, 1959], No. 14012/60. Class 69 (2). [Also in Group XXXI] An automatic hydrostatic transmission for a vehicle comprises a variable-displacement fluid motor 16 having a rotary output shaft 17 and a control means 19 to vary the fluid displacement thereof, and a source 12 of fluid under pressure connected to the motor and a servo-mechanism 18 connected by lost-motion means 27 to the control means to actuate the latter for increasing fluid displacement of the motor in response to increased fluid pressure resulting from increased resistance to fluid flow whereby the torque delivered to the shaft automatically governs the speed of the shaft. The source 12 consists of a constant displacement pump driven by a motor 10 and delivers fluid from a reservoir 14 to a line 13 connected to the motor 16 which may be of the axial piston type, the displacement of which can be varied by movement of a yoke 19. A line 13a connects the line 13 to the servomotor 18 which has a piston 22 connected by the lost-motion linkage 27 to the yoke. When the vehicle is running under light load, the yoke is urged by a spring to a position corresponding to minimum displacement. On shaft 17 encountering a load, such as a hill, the pressure rises in lines 13, 13a to move the piston 22 against a spring 24. Initial movement of the piston does not affect the motor but upon increased pressure, the lost motion is taken up and the yoke is moved to increase the fluid displacement of the motor and the torque applied to the shaft 17.

Abstract: 514,642. Compounds of unknown composition. SCHERING AKT-GES. (formerly KOKSWERKE UND CHEMISCHE FABRIKEN AKT.-GES). May 11, 1938, No. 14080. Convention date, May 11, 1937. [Class 2 (iii)] Oestrogenic compounds are obtained by polymerizing alkylene phenols and isolating the substances of oestrogenic activity from the reaction mixture, for example, by fractional distillation. In example (1), p-propenyl phenol is dissolved in acetone and a few drops of concentrated sulphuric acid added. After allowing the mixture to stand for about 24 hours at warm temperatures, it is poured into water and the oily precipitate extracted with water. The ether solution is freed from acid by washing with water and bicarbonate solution. After distilling off the ether an oil of oestrogenic activity of 1 vat unit per mg. is obtained. The oil may be purified by high vacuum fractional distillation. In example (2), p-propenyl phenol is subjected to a distillation in a vacuum of 1 mm. The first fraction is recrystallized from water and allowed to stand for seven montbs exposed to sunlight at warm temperature. A brown viscous oil is produced which shows strong oestrogenic activity and is purified as in example (1).

Abstract: 1,168,948. Nibblers. A. J. SMITH. 25 March, 1968 [10 April, 1967], No. 14369/68] Heading B3W. [Also in Divisions B4 and B5] An impact tool such as for driving nails, sawing, gauging or nibbling comprises a driver 86 connected to a piston 88 reciprocable in a housing 54 and adapted to be rendered inoperative when the driver is in an extended position and actuated to sequentially move the driver to a retracted position and thence to an extended position whenever the driver is displaced inwardly from the extended position. The piston is slidable in a movable cylinder assembly 98 having a ring portion 108 for co-operation with a slidable sleeve 114 and an exhaust bore 102 co-operable with spigot portions 128 and 126 formed on the piston and housing respectively. With the tool in the position shown in Fig. 4 air is fed from an inlet 120 into a chamber 134 via a passage 130 thereby maintaining the sleeve 114 in sealing engagement with a seal 64. When the end 17 of the driver 86 is pressed against the head of a nail to be driven the housing moves downwardly so that the air acts on the underside of the piston 88 via ports 136. As the piston rises the air above it is exhausted via the bore 102 until the spigot 128 closes the bore and the cylinder assembly 98 is lifted by the piston so as to exhaust the air below the piston via ports 138 (Fig. 7, not shown). Pressurized air trapped between the piston and cylinder head 100 then forces the sleeve 114 downwardly so as to allow air to pass to the top side of the piston via slots 142 and effect a hammer stroke. The tool continues to re-cycle, as long as hand pressure is applied to the housing, until a spring-loaded guide 74 abuts a washer 72 (Fig. 11, not shown); the thickness of the washer may be varied in order to adjust the depth of penetration of the nail head into the workpiece. In a modification, an additional trigger-actuated valve (208, Fig. 15) may be fitted in order that the tool can be selectively operated. In this embodiment the end 17 of the driver is adapted to co-operate with an anvil 202 and thereby used as a punching or nibbling tool.
